I saw a few of those places while driving and my opinion was negative, but still was curious. My curiosity grew over time but didn't dare to go in. My idea (yes as a guy) was drunk not so friendly folks, drugs, mafia, etc. My interest vanished but the curiosity remained. Then we have a reunion with friends, mostly coworkers and some suggested going to one of this places, well, let's try. One of the top places at the time was picked, it was a popular place, like a new disco.
First security check, it felt like going underground. Then, surprise!! nothing was as expected. There was music (not loud), bar, tables, chairs, all clean and pretty.
Most men were... talking Zzzz. Some prostitutes were at the bar, some were talking and laughing with the guys at some table, some were at the sides talking with each other, all of them dressed pretty, most of them fully dressed, very few showed a bit of their breasts from time to time. Some tables had men alone, drinking but not drunk. Some other tables had men talking, group talk, not drunk.
Honestly to my taste it was way better of what I expected. We ended on a sort of living room talking, laughing, healthy stuff actually. Some women walked around and then one of the guys said he was going in. Trust me this gets better. The older guy told him "don't", well the guy didn't listen. Then the older guy said "
poor X, he is going for sex but he wants something else, as usual he will come out with a smile, then laughing, then serious and then he will leave...", actually that happened. The guy was in the process of divorce, got out, laughed, then got serious, then left the place. No I didn't go in with any prostitute.
I went to a few more places like that out of curiosity with friends. What we saw was surprising, there was music, people talking, some laughs, etc. In some places there were men alone, serious, like thinking. In other places there were men also alone CRYING... in very few places there were drunk men, there are policies for that, encouraged to drink and get women but not to get drunk, they are usually invited to LEAVE.
At first I thought it was sin city

I was wrong, those are mostly places to chill out. Drinks are expensive, you are not forced to have sex, I mean you can go in and stay for a long as you like. There is heavy security all around, and no, I never saw no drugs over any place. Some of those places offer shows, dancing, one was quite artistic actually, others were... funny, inviting men from the public to make fun of them, some men are invited to dance, and sometimes they do this contests where you can win money, drinks or some time with X woman. Not what I expected. I accidentally found the BF of a friend there, I was in a relationship so it was fun to see each other and make the sign of "we are not here", and no, nobody had sex. I also saw a woman who worked at a bank, I got her number, never called.
My favorite topic? yes, because not a single woman I know as a friend believes this, they have strong denial on how irrelevant the description is, yes, a place to chill out. Then technology evolved and small cameras appeared (you are safety checked for this, is not a game, and cell phone use is monitored, no video allowed), the thing is some dudes managed to record video and uploaded it to the web, local places, it was fun to watch. So I shared this to some female friends, it matched everything I told them about the places, it was difficult for them to believe it.
Places vary on budget, lower budget? drunk people start to appear. That's it, believe it or not.
